I'm planning to build my own NAS and now decide to use Unraid instead of TrueNAS because ECC memory will be important to ZFS compared to other filesystems. (I saw this from a lot of discussions)
My question is why? I know ZFS rely on RAM for caching, but why ZFS is more vulnerable to memory corruptions? And why other systems like unraid and btrfs are not as emphasize ECC memory?
It's quite interesting to see two major voices. People from TrueNAS side suggest you must have ECC memory if you care about your data. But people from unraid side said ECC it's not worth the money.

I also think if I keep a list of hashes when I back up my data, then ECC might not be nessary at all.
The reason I don't want ECC is the cost. I have already blown up my budget with ASUS TUF Gaming motherboard and brand new intel 13th gen i5 because I don't want to gamble on cheap stuff.
I do plan on using those cheap stuff until I saw the comment saying it's frustrating when you have to going back and forth with the customer support team.
